稀土对45钢低温盐浴渗铬的影响

Influence of Rare Earth on Low Temperature Salt-bath Chromizing of 45 Steel

研究了稀土对45钢低温盐浴渗铬的影响。结果表明,稀土对低温盐浴渗铬有较强的促进作用,不仅能增加渗铬层深度,而且有助于其硬度的提高。

Influence of rare earth on low temperature salt-bath chromizing on 45 steel was studied. The experiment result shows that the rare earth can increase the depth of the chromizing layer and its hardness.The author thinks that the rare earth give an impetus to low temperature salt-bath chromizing.
